Product Overview


  • Dietary Supplement
  • Hypoallergenic

For individuals who need a more broad-spectrum digestive aid, Thorne Research offers Bio-Gest. Bio-Gest contains HCl, pepsin, pancreatin, and ox bile, which are important for those who need support for protein and carbohydrate digestion, and fat emulsification and absorption.

Hydrochloric acid secretion in the stomach does several positive things. It assists protein digestion by activating pepsinogen to pepsin, it renders the stomach sterile against ingested pathogens, it inhibits undesirable overgrowth in the small intestine, and it encourages the flow of bile and pancreatic enzymes. Hydrochloric acid also facilitates the absorption of a number of nutrients, including folate, vitamin B12, ascorbic acid, beta-carotene, iron, and some forms of calcium, magnesium, and zinc. Numerous studies have shown hydrochloric acid secretion in the stomach declines with advancing age. Overuse of antacids can also lead to low levels of hydrochloric acid in the stomach, which can result in poor protein digestion. Thorne offers hydrochloric acid and pure pepsin from a porcine source. Unlike many supplement companies, the pepsin utilized in Thorne's product is pure, undiluted, and lactose-free.

Pancreatin is a mixture of several digestive enzymes produced by cells in the pancreas. Pancreatin is composed of amylase, lipase, and protease. Pancreatin production and secretion by the pancreas is essential to digestion and absorption of numerous nutrients, especially fats.

Situations such as illness, gall bladder removal, overuse of antacids, and normal aging can contribute to insufficient secretion of stomach acid, pancreatic enzymes, and bile, and can adversely affect digestive enzyme activity and lead to heartburn, gas, bloating, and other symptoms of gastrointestinal discomfort.

Maldigestion can lead to digestive problems and poor absorption of nutrients, resulting in vitamin deficiencies (particularly fat-soluble vitamins like vitamins A, D, E, and K). Food allergies can develop when inadequately digested proteins are absorbed through the gut. As large proteins are absorbed intact, the body might recognize them as foreign and create antibodies to them, resulting in an allergic response to the food. An individual who has frequent indigestion should make sure to have adequate enzyme support.

The best but beware of its potency

Posted by Suppster on Jan 21, 2017

Helps to get those nutrients from your food. And especially during stressful times that you cant avoid or manage (priority is to manage your stress!), helps a lot since stress makes digesting poorer, which can make the food sit in your stomach for a whole day, can cause bloating and gas et . Helps enhance appetite too so you don't eat too little. Be careful with the dosage, this works even if taken after a meal.

Magic in a bottle

Posted by 5596384735393222543 on Jan 18, 2017

I have been using this product since October. The difference in my digestive health is amazing. A naturopath initially started me out on berberine and Biogest, then cut out the berberine after a month. I have gone from having diarrhea and cramping four to five times a week for years - I was diagnosed with IBS - to a single one-day episode since I began the regimen. My profile includes having had gallbladder surgery and probable sensitivity to some grains, so I can't say that your digestive issues will respond as well as mine have to Biogest, but it has made a huge difference in my life. There are many other products available, but I haven't seen any that have identical ingredients. I'll stick with Biogest!

Not really sure it works. I'll try something else to help digestion next time.

Capsules are made out of SYNTHETIC material Hypromellose!!

Posted by 5026282378517886029 on Dec 10, 2016

I didn't experience much improvement with my digestion. Me eating healthy diet helped more than these capsules. Also the buyers of this supplement need to be aware that these capsules are not entirely veggie caps. One of the casing's component is Hypromellose (Vegetable grade). Hypromellose is short for Hydroxypropyl Methylcellulose (HPMC). Hypromellose is loosely described as vegetable-derived cellulose. It’s a synthetic version of gelatin derived from cellulose made from plant fibers such as wood from tree trunks that’s been extracted and then treated with various chemicals throughout the production process to make a polymer. The resulting HPMC is then mixed with water to form the vegetarian capsule material. The FDA has determined it GRAS (generally recognised as safe). This basically means HPMC isn’t required to be adequately studied for proof of safety. So this begs a question, why would anyone in their right mind eat anything that contains Hypromellose in any shape/form or quantity when no one has tested it for safety in humans!
